1. Jim has a frontal cross-section of 2.00 m high by 0.500 m wide and can run at 4.00 m/s and swim at 1.00 m/s. His drag coefficients in air and water are 1.30 and 1.10, respectively. What speeds should Jim run and swim at to be most efficient? Assume Jim's BMR is 0.300 MJ/h.

2. Determine which of the following expends the most energy over a 20.0 mi course:
a. A 126 kg pedal-powered aircraft flying at a speed of 15.0 mph with a locomotion transport number of 0.134.

b. A fast walking 75.0 kg person walking at a speed of 2.50 mph,

c. Determine the energy expenditure rates of the person powering the aircraft and the person walking and comment on the feasibility of maintaining these rates over the 20.0 mi course.
